Q26.4: The heating element of a hair dryer dissipates 1500 W when connected to a 150 V outlet. You may want to review (Pages 841 - 843) .
What is its resistance? Express your answer to two significant figures and include the appropriate units.
Here,
Power , P = 1500 W
Voltage , V = 150 V
let the resistance is R
as P = V^2/R
R = V^2/P
R = 150^2/1500
R = 15 Ohm
the resistance is 15 Ohm

A heating element in a toaster dissipates 800 W when run at 110 V. How much charge passes through the heating element in 1 minute? Please show all of your work. Express your answer to two significant figures and include the appropriate units.
The heating element in a hair dryer is essentially a wire whose resistance causes it to become red-hot when a current exisits in it. Such wires are usually made of nichrome (a nickel-chromium alloy), whose resistivity is p=1.0*10^-6 ohm*m. (a) Suppose one such wire has a diameter of 0.30 mm and a resistance of 9.0 ohm. What is the length of the wire? (Note that wires like this in a hair dyrer tend to be coiled around to save space)...
